Most Used Shooting Mode for Weddings...

I am curious as to what mode most of you use when shooting weddings...
My guess would be Aperature Priority to control over Depth of Field but wanted to get a consensus from all of you wedding photographers.
Also, how many of you utilize Auto ISO vs manual setting ISO?
Thanks!

I'd go for aperture anytime, so I can open with wide open f values, to really put the focus on the most important people of the day. ISO on manual - you're not really changing light situations by the minute, are you?

Manual ! this comes from having shot manual film cameras for years. My biggest gripe is the newest breed of photographers who shoot auto only. They do not know how varying the f-stop, ISO, shutter speed will affect the image.

Indoor or outdoor - Av and M.
I guess , the key is to understand how your camera meters the exposer at any lighting situation and the result should meet your expectation (I mean - you have to know what should be exposed correctly before going to M).

Shooting ambient, I like aperture priority along with auto ISO in a 5DII. It makes the same choices I would. It tries to keep the ISO as low as possible while maintaining at least a 1/[focal length] shutter speed. It's faster at doing that than I am. I then just adjust the compensation as needed.

Things change in the dark, though... I can't compensate enough to get a short shutter speed in the dark when relying mostly on flash. Then I go manual everything.

Since I don't like to have to switch modes on the move, I tend to go back to the safety of manual most of the time. Everything can be done in full manual. No other mode offers that kind of simplicity.

With the 5D, I shot program, aperture priority, and manual, with manual ISO of course.

It's often hard to convince people, but Program mode gives almost as much control as any other mode. You just have to change your mind to use it in an aperture or shutter priority kind of way, and select a compensation based on what you know the meter is reading. It's sometimes refreshing to change how you think about controlling the camera. Just not in the middle of a job.

mostly manual, sometimes on my second camera I will use aperture priority, because it might be a long time between shots with it and when I want it, I want it quick, so I am willing to sacrifice a bit of control for speed in that circumstance.

Manual everything except White Balance. I can't remember the last time I shot on an auto mode.
You are taking photos to achieve your visions, your camera does not know what you want the images to look like.
